Sh!t , I’ve been trying to avoid this topic! Listen there have been uncountable cases of genetic mutation like for example frameshift that ends up causing many deceases, Siamese twins, premature births, a race of intelligent animals that are destroying nature itself, just because it happens doesn’t means that it is automatically right..
Exactly what makes you think you have the right or authority to decide what is or is not right? If something is not right from the POV of nature, it gets eliminated by natural selection. yet homosexuality in animals is a fairly spread phenomenon and as such it proves your theory incorrect.
An estimate of 15-20% of the general male population and up to 80% of the female human population are supposed- by Kinsey who have the data to back it- to be in various degrees bisexual to homosexual. That is not an exception. That is a genetic trend which may as well be nature's response to overcrowding.
